BOTTLE-FILLING MACHINE.

To all whom/it may concern:

. Be it" known that I, GUSTAV STRANDT, a citizen of the United States, residing at Milwaukee, county of Milwaukee, and State of Wisconsin, have invented new and useful Improvements in Bottle-Filling Machines, of which the following is a specification.

My invention relates to improvements in bottle filling machines, with special reference to that class of machines in which a rotary supply tank is located above a bottle carrier rotating at the same speed, the tank having a set of outlet nozzles in its bottom continued rotation of the supply tank and adapted for registry with the bottles, and

carrier then returns such nozzle to the bot tle receiving station, where another bottle is inserted. The spring actuated nozzle valve closes when the filled bottle is delivered and it again opens when the empty bottle is brought into registry.

In machines of the above mentioned type, the residual liquid in the nozzle when the filled bottle is withdrawn has been permitted to waste, together with such liquid as may escape from the tank past a'valve which has closed imperfectly or before the valve has become fully seated; This liquid has not only been wasted but it has tended to render the premises unsanitary, especially where milk or other liquids are being handled which deteriorate quickly after exposure to the atmosphere.

, The object of my invention is to provide means whereby liquids dripping from the valves or nozzles of filling machines between the delivery and receiving stations may be saved and unsanitary conditions avoided.

In the drawings, Figure 1 is an outline plan View of a bottle filling machine of ordinary'type to which my invention has been applied. Fig. 2 is a plan View of Specification of Letters Patent.

Application filed November 29,1915. Serial No. 63,935.

an attachment embodying my invention, with a portion thereof illustrated in horizontal section, the supportingshat't being also illustrated in section. Fig. 3 is a side elevation of the same showing a fragment of the supporting shaft and filling tank, and with a portion of the attachment partially broken away in vertical section.

Like parts are identified by the same reference characters throughout the several views.

The tank A. is provided with a series or annular row of depending filling nozzles D. It is supported and rotated by means of a shaft B which also supports and rotates the bottle carrier These parts may be of any ordinary construction and therefore need not be described with further lmrticularity.

The shaft B is provided with a tank sup; porting flange E, and a hanger sleeve. formed inseparable sections is secured thereto. The upper section F has a flange E at its upper end which is secured to shaft flange l) by bolts or screws 0. The lower end portion of the sleeve section F is provided with an an nular flange f below which this sleeve section is thickened, shown, at 11", to facilitate connecting thereto a lower sleeve 'section G. Sleeve section G is provided with a flange g .which abuts the lower end of the hub F and is secured thereto by screws or bolts 9'. The two flanges f and r are therefore spaced apart, and provide an annular channel to receive a rotatable collar ll which is provided with a pair of outwardly projecting fork arms I sufliciently separated to allow a drip pan J to be inserted between them. This pan J is provided with ribs J, J" adapted respectively to engage the upper and lower surfaces of the arms I whereby the pan J may be supported from the fork arm. I in slip joint connection therewith.

The drip pan J is provided with late 'al extensions K and K in an arc corresponding with an arc of the circle in which the filling nozzles revolve. This pan is also provided with a projection M which is adapted to engage a stop rod N to prevent the pan from swinging rotatively with the shaftB owing to the frictional contact of the collar H with the hanger sleeve sections and flanges.

The drip pan J is supported in a normal position with its projection M in registry with the stop rod N in which position. it projects between the filled and empty bob t les and receives liquid dripping froinjthe nozzles between the deliverypoint and bottle receiving point. But "the liquid-collected in the drip pan may be returned to ply tank A. Preparatory to this operation,

the machine may be stopped and one or more filled bottles removed manually to permit the pan to swing Without striking them.

lhe pan 5 may then be replaced on the arms l and swung back to its appropriate posi tion in contact with the stop rod ll. Eythus providing for the removal of the pan, ll avoid the necessity of employing drainage ducts and additional receivers to collect the liquid escaping from the drip tank. It is very diflicult to keep drainage ducts in a sanitary condition, but with the removable pan above described, it is obvious that when the same has been removed from the sup-- porting arms, it may be thoroughly and quickly cleansed before replacing The rotative adjustment is required for the ma son that the pan is necessarily located. underneath the feeding and discharging; platform and therefore could not be readily removed by pulling outwardly from that point. err-- ing to the diiiiculty of engaging and disengaging it from the fork arms when in this position and also owing to the fact that it is then in line with the bottle feeding conveyor 1 or. any other devices located at the receiv ing station for the filled bottles. The newly inserted bottles would also be in the Way of such a removal of the drip tank.

With the construction above described, it

is obvious that any vertical adjustment of the tank A and shaft 13, such as may be required from time to time to accommodate bottles of difiering heights 0r sizes, will not affect the relative position of the drip pan, since by my improvement the drip pan supported by the hanger sleeve directly from the under surface of said tank; A.

l. The combination with a rotary bottle filling machine, of a pan supporting fork loosely supported therefrom and adapted to swing thereon, and a pan adapted for sliding engagement with the fork arms.

2. A bottle filling machine, including the combination with a vertically disposed rotary'shaft, of an annular fork support on circling said shaft, a fork having 'a collar Ways, ofa drip tank removably supported in. a position to receive drippin'gs from nozales PSWSSHlgEI'QlH registry Witlithe discharginpgu'ay into registry with toe receiving Way, and ,rneans for swinging said drip pan laterally from; such position preparatory to removing it from its support.

:5. A bottle filling machine including the combination. with a rotary shaft, a. tank carried thereby and provided with filling" 1mzles, a collar loosely encircling said shaft and supported therefrom, a pan supporting member connected with said collar and an detachabl connected with the su ort- P ing' member in a position to receive drippings from the nozzles.

6. A bottle filling machine including the combination. with a rotary shaft, a tank carried thereby and provided with filling nozzles, a collar loosely encircling said shaft and supported therefrom a pan supporting member connected with said collar and a pan detacnably connected with the supporting'inember in aposition to receive dripping fron's. the nozzles together 'With' "a stop adapted to prevent the pan. from rotating "with the shaft out of such drippings.

7. A bottle filling machine including the combination Wllillflrotary shaft, a tank can ricd therebycand provided with filling nozzles a collar loosely encircling said shaft and supported. therefroin a pan supporting member connected with said collar and a pan'detachably connected with the support ing' member in a posit-ion to receive drippings from the nozzles, said sha ft having a flanged hanger sleeve interposed between the shaft and collar and supporting the latter. 7 I
